Whales, dolphins, and porpoises have all evolved to use similar narrow beams of high intensity sound to echolocate prey. Far from being inefficient, this highly focused sense may have helped them succeed as top predators in the world's oceans.

A new study from the Department of Bioscience shows a surprising decrease in the proportion of females among four common waterfowl. Researchers are concerned about the uneven gender balance and predict it could have consequences for the populations, if the trend continues.
